Introduction
============
This data set contains photometric measurements of comet 9P/Tempel 1
from images taken with the Medium Resolution CCD Instrument during
the approach phase of the Deep Impact mission (from 1 May 2005 to
4 July 2005). These data, based on circular apertures ranging from
5 to 30 pixels in diameter, were derived from both science and
navigation images taken through clear filters.
Volume Format
=============
This volume has been formatted according to the ISO-9660 level 2
Interchange Standard for directories and file names.
File Formats
============
All text documents and other meta information files such as
descriptions, PDS object definitions, and detached PDS labels are
stream format files, with a carriage return (ASCII 13) and a line
feed character (ASCII 10) at the end of the record. This allows
the files to be read by various operating systems.
